Not knowing that my wife had gone on a trip with her close friends, her sister came over to play at our house, creating an awkward atmosphere. It would be bad to let her leave like that, so I decided to treat her to a meal. We ate together, drank alcohol, and talked. "Just because we've had a few drinks doesn't mean I'm going to kiss you, you bad girl. You're definitely a masturbation toy." My sister-in-law, who is easily swayed and submissive, has both her mouth and her vagina customized to my liking. I repeatedly had my way with her until my wife returned.
